BRUSH FOR DRESSING vVITALE/PS.

Specification of Letters Patent No. 15,308, dated July 8, 1856.

To all whom t may concern Be it known that I, SAMUEL TAYLOR, o-fCambridge, in the county of Middlesex and State of Massachusetts, haveinvented an Improved Brush for Sizing or Dressing lVarps; and I dohereby declare that the construction of the same is fully described andrepresented in the following specification and the accompanyingdrawings, of which;

Figure 1, exhibits a side view of the working end of a bristle as formedin accordance with my improvement. F ig. 2, exhibits the shape of theworking end of a bristle of a common warp dressing brush.

It is well known that in the construction of warp dressing brushes, thebristles thereof after being inserted in their block, are trimmed off sothat their points or working ends may be parallel to their holding blockand be mostly in a plane parallel to the side of said block.

In using a brush of this description, a difficulty is experienced incausing its bristles to pass between the threads of a warp during theprocess of dressing such warp; and this difficulty results from thefact, that as the 'working end of each bristle is cut olf square to thebody of the bristle, it when brought into contact with and down upon awarp thread will adhere thereto, and not pass by the same unless thebristle, by the process exerted on it is forced to spring off thethread.

In carrying out my invention, I bevel or chamfer off the working end ofeach bristle to an acute angle with the body or stock thereof, as shownat a, in Fig. 1, in which, A, exhibits the bristle, and such angle Iprefer to be 4,50 or thereabout, although I do not limit my inventionthereto, but make the angle more or less acute as circumstances mayrequire.

I would remark that my invention has no reference to brushes made ofuncut bristles or those having natural points, as bristles so pointedare not used in dressing warps, or if over used are liable to the objections of the square cut bristles or to those of a more seriouscharacter, as owing to their sharp points and the stiffness of theirstocks they will be more or less liable to penetrate and split the warpthreads.

I/Vhen a brush is made on my improved plan, each of its bristles whenits working end is borne down upon the warp thread will readily glancetherefrom, so that the brush can work up between the threads of a warpwith great facility in comparison to what it would be were itconstructed so as to have its bristles square in the ordinary way.

In the process of making a brush with beveled pointed bristles, eachbristle after being inserted in the block, and preparatory to, and whilebeing cut off may be bent down to an angle of about 15 with the block sothat the knife or cutter while passing through the mass of bristles maycut each bristle diagonally or slantwise.

I claim My improved warp dressing brush as made with the external endsof its bristles cut slantwise or beveled with respect to their stocks inmanner as specified, and for the purpose of enabling the warps to enterthe brush with more facility than would be the case were the points cutoff square in the usual way.

In testimony whereof I have hereunto set my signature this third day ofJ une, 1856.
